Will this support plan wind up warping later? 

I'm in a climate controlled basement. Temps do vary by 10 degrees or so summer to winter but humidity level is relatively constant. Plywood deck is 3/4 inch birch cabinet grade. I had to modify my support structure so I now have the upper deck here supported on the sides of 1x2 strips ripped from plywood. I needed the extra height for the deck, and I new with a 24 inch wide section that the upper deck needed some lateral support under it or it would sag.

Another SD40-2 is returning to Florida East Coast after refurbishing in the "Heritage" scheme.

SD40-2 720 was photographed at Waycross, Ga in route by Allan Williams, Jr.

Since I'm not a fan of ballasting, on my last layout I sanded down cork roadbed to a more proto profile and left it unballasted.  There was enough color variation among the little bits in the cork that it looked ok to me.

I've started a new shelf switcher and don't want to bother with sanding cork again, so I'll probably use thin cork sheet (roll) for roadbed.  The color of the sheet is not as realistic looking to me as the cork roadbed though.

I haven't posted in a while, been busy with other things. Since my original post about restoring an old, crusty MDC 0-6-0 (read it here), I have cleaned up all the parts and rebuilt the motor...
